SPECIFICATION forming part of Letters Patent No. 477,801, dated June 28,1892. l

Application 'filed December 26, 1891. v Serial No. 416,158. (No model.)

110 all whom t may concern.:

Be it known that I, HENRY B. HAYES, a citizen of the United States,resid-ing at Woburn, in the county ofMiddlesex and State ofMassachusetts, have invented certain new and useful Improvements inlVindoW-Fasteners, of which the following is a specification, referencebeing had therein-to the accompanying drawings.

My invention has forits object to produce a window-fastener by means ofwhich a window-sash may be secured firmly at any point in the frame,which shall be durable and easily'operatd, and by means of which, also,the sash may be pressed and held against the frame, so as to morecompletely exclude Vcoldv air, dust, and the like.

My invention consists in the novel construction and combination'of partsconstituting an improved and serviceable window-fastening, all ashereinafter set forth, and as is' more particularly pointed out in theclaims which are appendedhereto and made a part hereof.

I have shown my invention in the best form now known to me intheaccompanying drawings, to which reference will be made in thefollowing description, and in which- Figure l is a front elevation of mydevice applied to a window. Fig. 2 is a section on line 2 2, Fig. 1.Fig. 3 is a similar section, but showing the securing-bolt withdrawnfrom contact with the sash and also showing the free end of the boltwhich cornes in contact with the sash as provided with a facing ofrubber or similar suitable material. Figs. 4. and 5 are perspectives ofthe casing and basepiece. Figs. 6 and 7 are respectively a plan and sideview of the cam and its thumb-piece. Fig. 8 is a perspective of thebolt.

A represents a window frame or casing, and B a portion of a window-sash.

My device, as shown, consists chiefly of four parts-a bed-plate or basec, a case or cover d, a sliding bar or bolt f, and a cam gpro vided witha suitable projection by means of which the cam may be operated by thethumb The base c is preferably of the shape shown and is provided withtwo lugs or projections h to receive screws by means of which the devicemaybe firmly secured in place. The cover or case dis in form acounterpart of the base c, it being also provided with lugs h', whichoverlie those on the bedplate c, so that the retaining-screws will passthrough the lugs on both the cover d and plate c. The sides of thecover,l extend downwardly from the top portion thereof, as shown, Fig.4, for the reception of the sliding bar or boltf, forming a cavitywithin which said bolt orbar may slide. The end of the bolt f which isdesigned to come in contact with the window-sash is enlarged or providedwith a shoe 7c,so'that it may have a broad and substantial bearingagainst the sash. The rear end of the bolt f is in contact with the camor eccentric g, which for greater strength is pivoted on a post Z, whichis preferably castintegral with the base c. The cam is provided with aprojection m, by means of which it may be readily operated by the thumband finger. A hole for the reception of a screw u is made through thecoverd and post Z. This screw n may also pass into the window-frame andmay thus serve asan additional means for securing the device rigidly inplace. As it is desirable that the sliding bar or bolt f may as soon asthe device is freed clear the window-sash, in order that' when the sashis moved the foot of the boltwill not bear against the sash and scratchor deface it, I provide a spring p, which is laid within a slot 10length wise of said bolt f, said spring bearing at its rear end againstthe end of the said slot and at its forward end against the screw a",which passes through the cover d and through one end of the slot in thebolt f. When the cam is turned to force the bolt outwardly against thewindow-sash, the spring p is compressed, and as soon as the cam isturned in the opp:L site direction to free the bolt the spring operatesto retract the slidingbolt f, as will be clear.

To render the grip of the bolt f on the sash more secure, as also tolessen the danger of defacin g the sash, the contact-face of the footIOO sition, and if the Window be olosed.` forcing p 2, Thewindow-fastener composed of the the sash against the casingwi-thsuchpressure ,base o, formed with thefpostl; and the lugs h as to eectivelyexclude cold air and dust'. h, the cover d, formed With lugs 7L h', theslid- The employment of acanl for actuatingand ing bolt f, the cam g,pivoted on post l and 5 holding the sliding bolt insures against theoperating to positively press the bolt outward zo freeing of thefasteners by continual jarring into engagement with a Window-sash, thesuch as fasteners are subjected tor in-railwfayspringpifor retraotingthe bolt, and the screws cars. n and o, substantially as described.
